Storage in the Digital Home We live in a digital world. We digitally create, record, edit, share and save practically everything from the movies we watch, to the pictures we take, to the files we store. Today’s digital home demands the ability to do all of this with high-quality digital content. PC storage plays an important role in meeting this demand. Intel®^ Matrix Storage Technology provides improved performance and reliability for systems equipped with Serial ATA hard disk drives, today’s optimal PC storage solution.
The RAID Solution Optimum disk performance can be found in a core technology from the enterprise server arena known as Redundant Array of Inexpensive Disks (RAID). Originally developed by a research team at the University of California, Berkeley, RAID harnesses the power of multiple hard drives working in unison to deliver greater performance and redundancy.
While the storage performance of a single-drive system is only as fast as the physical limits of the single drive, a RAID array can read and write data in parallel from multiple drives. This configuration, known as RAID 0, delivers exceptional storage performance and optimizes data transfer to provide a richer digital media experience.
Multiple drives in a PC can also provide added protection from disastrous hard drive failures by mirroring all data among two or more drives. This configuration is known as RAID 1. While RAID 1 capability does not provide the same level of performance as RAID 0, it is faster than a single disk, and adds value by helping to keep the system functional in the event of a hard drive failure.
RAID 1 capability is an ideal solution for home PCs containing valuable content that would be at risk in the event of a hard drive failure. With digital photography and video editing becoming commonplace, more personal memories such as photos and recordings are being stored on the PC. RAID 1 technology can protect these digital memories from hard drive failure.
Performance with Protection: Intel ®^ Matrix RAID Technology Intel innovation continues with the introduction of Intel ® Matrix RAID Technology, which combines the benefits of RAID 0 performance and RAID 1 protection on two hard drives. For example, games and video editing benefit from improved performance, while valuable personal photos and financial records can be better protected from a drive failure.
The Desktop Storage Solution: Intel®^ Chipsets with Intel®^ Matrix Storage Technology Intel is making RAID and advanced Serial ATA capabilities an affordable reality for desktop platforms by offering Intel Matrix Storage Technology as a value-add feature on Intel’s new line of desktop chipsets. Intel Matrix Storage Technology, based on tools from Intel’s enter- prise RAID products, is the industry’s first RAID capability in the chipset, and uses the latest Serial ATA disk interfaces for increased performance headroom.
Intel Matrix Storage Technology includes support for Serial ATA Advanced Host Controller Interface (AHCI), providing advanced features such as native command queuing, hot plug, and power management. Native command queuing, when paired with capable hard disk drives, increases storage performance on random workloads by allowing the drive to internally optimize the order of commands. This provides increased performance for today’s multitasking environments and demanding applications.
Intel Matrix Storage Technology can be found on select platforms based on the Intel®^ 915G and 915P Express chipsets and the Intel ®^ 925X Express chipset. Contact the platform manufacturers directly to verify which of their products offer Intel Matrix Storage Technology.
